For the first time in weeks, retail pump prices for both diesel and gasoline dropped across most of the nation, according to data tracked by the Energy Information Administration (EIA). While gasoline prices fell by 2.2 cents nationally, compared to pump prices on Memorial Day, diesel's decreased price was much smaller: 0.3 cents on average across U.S. on-highway retailers.
After three straight weeks of increasing diesel prices, the national average dropped from $3.288 on May 28 to $3.285 on Monday, June 4. Monday's average diesel price is 72.1 cents higher than it was this week in 2017.
Most U.S. regions saw small decreases – less than a cent per gallon – in diesel prices this week, according to the EIA. Only the Gulf Coast and Rocky Mountains regions saw small increases of less than a penny per gallon.
The West Coast, home to the most expensive diesel in the nation, stayed steady at $3.784 per gallon. California, which is disproportionately responsible for the pricey diesel out West broke the $4 mark for the first time this year. It now costs an average of $4.003 per gallon for diesel in the Golden State. When removing California from the West Coast equation, the average price for diesel is $3.508 (down 0.6 cents from last week) per gallon.
At $3.055 per gallon, the Gulf Coast still boasts the least expensive U.S. on-highway retail prices for diesel, according to the EIA.
